Regulation relationship between interest rates and exchange rates to maintain Algerian economy's competitiveness.

This study's objective is to use econometric analysis to quantify the effect of interest rates on Algeria's exchange rate from 1990 until 2021. Based on the Autoregressive Distributed Lag (ARDL) model, which uses the exchange rate as the dependent variable and the local interest rate and interest rate differentials as independent variables. The study found no long-term association between the independent variables (local interest rate, interest rate differentials) and the dependent variable (exchange rate) based on the estimation of the econometric model. The local interest rate has a positive and noteworthy short-term influence of 11.83% on the currency rate. Additionally, the study suggested that interest rate liberalization was necessary.
